Jetflow Air Movers

The Jetflow Air mover is a very effective ventilator for mines, tunnels and confined spaces, where it has gained a worldwide reputation for performance and reliability. The Jetflow Airmover operates from a compressed air line and produces a high velocity jet of air which is ideal for penetrating stagnant areas. It’s effect is to dilute and remove methane, explosive fumes and other hazardous gases. Airborne dust is disburse and the effective temperature and humidity reduced making the working area a safer, healthier and more productive place in which to work.

101 Series – Haskel Air Booster version

Haskel Air Booster version of our popular Trident 101 series system.

Haskel Air Booster

This unit has been fitted with the Haskel AAD-2 series air driven air booster pump. The part number includes the suffix -2. This means that the booster will boost or amplify the incoming air pressure two times. So if you have 100 psi air in your workshop or process you can increase it to 200 psi. Perfect for getting the most out of your air driven test pumps!

We have used the term “Air Booster” here as a common term for “Air Amplifiers”. Have a look at the range from Haskel and SC Hydraulic here.

Haskel Gas Booster

Haskel’s single acting, single stage gas booster is the smallest and lightest with pressures to 39,000 psi. Double acting, single stage provides twice the delivery of a single stage booster. Two stage models are used for high gas compression ratios.

Haskel High Flow Liquid Pumps

Haskel High Flow Liquid Pumps include the 2, 2,2 and 3HP pumps. These are the double and triple air head pumps that are based on the 5 3/4 inch drive pump. Call us for a bit of an explanation on how these pumps work.

Air Operated Directional Control and Release Valves

These directional control valves are basically family with common characteristics and benefits.

They are seated poppet or ball design for virtually zero leakage at high pressures with low viscosity fluids. They are not “bubble-tight’’ on gas. Note: Normally open models will generally hold a tighter seal on low viscosity liquid or gas because seating force does not depend on inlet pressure.

They are directly air-actuated for ideal system compatibility in wet or hazardous areas, or when used in air driven pumps or boosters. Yet, if electronic or electrical control is preferred, they can be actuated with any of the wide selection of sub-miniature 3-way solenoid air valves available from many manufacturers.

They employ the same basic area ratio principle used in Haskel pumps enabling high forces to be easily and directly controlled from low pressure plant main or instrument air.

Although not normally considered for pressure control, all of the normally open 2-way models can do double-duty in a circuit by also providing a safety relief function simply by installing a small air regulator in their pilot line.

Haskel Air Pilot Valves

Haskel Air Pilot Valves are pressure switches. These units produce a pneumatic signal up to 150 psi at any sensing pressure within their adjustment range. The signal valve may be piped normally open, normally closed*, 3-way or 2-way depending on the model.

All models use a 2-position poppet-type air signal valve which is shifted from its normal position by a rod from the sensing end which first must overcome an adjustable force spring or air regulated dome loader.

Haskel Regulating Relief Valves

Regulating relief valves were originally developed in response to the need for accurate regulation of high pressure at low flow without the “chatter” often encountered with valves this size. They are a differential area poppet design with a high ratio between seal and seat area for smooth control, repeatability and low deadband between crack and reseat pressure. The configuration also makes the control settings virtually unaffected by downstream outlet pressure. This enables the valves to be also used for back pressure control (upstream pressure controller) or a sequence (priority pressure valve). Materials of construction options seen in the chart of model numbers provide selections for most liquids including plain water plus most industrial gases including pure oxygen. Note that the nylon insert seat models are recommended for all gas applications below 10,000 psi. The 15700 series valves for service up to 60,000 psi are normally used as safety valves at these pressures. Although not rated as bubble tight, they do an excellent job holding high pressure gas due to their precision poppet and hardened stainless steel seat with heavy silver plating.

Stainless Steel Check Valves

Combining the best features of durability and positive sealing, these unique valves are constructed throughout of 316 Series Stainless Steel for the high corrosion resistance essential in the chemical, processing and power generating industries.

PTFE seat seal for positive bubble-tight sealing (with gas) from cryogenic to 190 degrees Celsius temperatures. Seals also available for radioactive environments, or up to 500 degrees Fahrenheit steam. Can be furnished without soft seat for higher temperature steam service.

Sizes 1/4” to 1” use ball, and reduced interior, the larger sizes (1-1/4”, 1-1/2” and 2”) use a poppet. Cracking pressure is 1 – 4 psi. Larger valves can be furnished for flange mounting to customer specifications on special quantity orders.

Semi-soft means the check ball or poppet initially seats the PTFE, but after the PTFE deflects a slight amount, the ball or poppet comes to rest against the metal seat so that the PTFE does not have to absorb the full load of the high pressure.

Internal passages have flow capacity equal to or greater than double extra heavy pipe of the same size that would be required to carry the rated pressure.

Typical of good Haskel design is the removal of springs from the flow path. The larger spring is outside the flow and simply provides a preload for the disk. The smaller spring, inside the cage, actuates the ball or poppet but the flow, which is routed through the cage windows, misses the spring entirely. This is why the valves will stand extremely high stock loads and have been tested at rapid high stock up to 2 million cycles without failure.
